Answer:

The percent of C is equal to 71.62%, the percent of O3 is equal to 28.38%

Explanation:

To find the percentage of C, you just have to divide the amount in grams of C, on the weight of the tablet and multiply it by 100, so that the answer is in percentage, as follows:

%C = (0.4655 g C/0.65 g antacid tablet) x 100 = 71.62%

%O3 = 100 - 71.62 = 28.38%

The vapor pressure of liquid acetone, CH3COCH3, is 100 mm Hg at 281 K. A 6.06E-2 g sample of liquid CH3COCH3 is placed in a clos
Lynna [10]

Explanation:

According to ideal gas equation, product of pressure and volume equals the product of number of moles, gas constant and temperature.

Mathematically,     PV = nRT

where          P = pressure,               V = volume

                  n = no. of moles,         R = gas constant = 0.0821 atm L/mol

                   T = temperature

Since, it is known that number of moles equal mass divided by molar mass.

Hence, number of moles of given sample of acetone are as follows.

              No. of moles = \frac{mass}{\text{molar mass of acetone}}

                                    =  \frac{6.06 \times 10^{-2}}{58 g/mol}

                                    = 0.104 \times 10^{-2} mole

Therefore, putting the values in ideal gas equation as follows.

                         PV = nRT

P \times 0.36 L = 0.104 \times 10^{-2} \times 0.082 atm L/mol \times 281 K

                           = 0.359 atm

In 1 atm equal to 760 mm Hg. So, convert 0.359 atm into mm Hg as follows.

                  0.359 atm \times \frac{760 mm Hg}{1 atm}

                       = 272.84 mm Hg

Hence, pressure of the ideal gas will be 100 mm Hg + 272.84 mm Hg = 372.84 mm Hg

Thus, we can conclude that the ideal gas pressure in the container if all of the liquid acetone evaporated is 372.84 mm Hg.
